Constantly blowing bulbs

We installed 9 well lights within a sidewalk 2 weeks ago. Since then we have gone through 12 bulbs. They are the PAR 36 style bulbs that have the stacon connectors. The bulbs keep blowing(commonly referred to as smoked). The volts at the fixtures are reading 11.3- 12.0v. Only 3 fixtures per run on 10 wire. Anybody have experience with this? I am stumped and the manufacturer has yet to come up with something.

PAR 36 Blowing

I think they are getting too hot. What is the wattage? Try using a bulb of lesser wattage. This is especially more of a problem if the well light is completely sealed. (water tight).

too hot

Higher wattage will put out more heat. If the space for the bulb is designed for say a max. wattage of 25 and a 50 is used, it might damage the fixture and shorten the life of the bulb. Wattage is also a function of current draw not just voltage.

These are 25watt bulbs. The cover is an open grate and there is a 6-8" air space underneath. So I don't think overheating is my problem.

Chesie, have you tried changing the bulbs to another manufacturer or run number. Defective product does make it to the street a lot. Is there a time that has been witnessed when these lamps are smoked? At startup, when they have been on all night, or perhaps when the sprinklers are hitting them first thing in the Am if they are dusk to dawn. You say they are mounted in the sidewalk. What type of walk? Concrete, paver or dry laid stone? Maybe some pictures would be helpful to understand. What brand of fixtures are you using? Could you replace one fixture with another brand to determine if it is the fixtures that may be causing your headache? If the lamps are getting "smoked" and nut just burning out, that would be indicative of a short. Are all the fixtures blowing lamps or just certain ones? Let us know your progress.

cooked bulbs

In view of these details, I like Kirk's thoughts. Switch to a different brand of bulb. Check if the water is soaking the bulb .....?

some transformers do not operate properly if there is a light within 4 feet of it. What brand of lights are you using?

I had a huge problem with the 18 watt halogen and the 25 watt GE par 36 lamps. GE is no longer manufacturing the 18 watt lamp and I switched to sylvania. Since I switched, I have had no problems.
